Web17 mrt. 2024 · Transfer RNA, or tRNA, is a specialized RNA molecule that brings amino acids to the ribosome for protein production. In eukaryotic cells, tRNA is made by a special protein that reads the DNA sequence and makes an RNA copy, or pre-tRNA. Pre-tRNA is processed once it leaves the nucleus. How does mRNA become tRNA? Web7 mei 2024 · The translation is the second part of the central dogma of molecular biology: RNA --> Protein. It is the process in which the genetic code in mRNA is read to make a protein. The translation is illustrated in Figure 6.4. 6. After mRNA leaves the nucleus, it moves to a ribosome, which consists of rRNA and proteins.

WebLike DNA, RNA is made up of nucleotide consisting of a 5-carbon sugar ribose, a phosphate group, and a nitrogenous base. However, there are three main differences between DNA and RNA: RNA uses the sugar ribose instead of deoxyribose. RNA is generally single-stranded instead of double-stranded. RNA contains uracil in place of thymine. Web18 jul. 2024 · Transfer RNA (tRNA) is a molecule that carries a single amino acid and a coded sequence that acts like a key. This key fits into a specific sequence of three codes on the mRNA, bringing the correct amino acid into place. Each set of three mRNA nitrogenous bases is called a codon.
